Kern.js

Lettering.js has recently added a gallery of sites that use their styles; it’s worth checking out, too.

Zoomooz

Zoomooz (GitHub: jaukia / zoomooz) by Janne Aukia makes elements on a page “zoomable” — the page apparently zooms into a smaller slice of content. The example on the project’s homepage consists of small tiles which zoom in when clicked.

Amplify

Amplify (GitHub: appendto / amplify, MIT/GPL) provides a unified API for data sources. A set of components are provided for managing data-related tasks: the store component manages client-side data, a request component provides enhancements to jQuery’s Ajax library, and there’s also a pub/sub system. It’s like a Swiss Army knife for data.
